This series is now published outside of Japan.
Let's have a look: Italy has been the first one to schedule a release. The publisher has changed and is now GP Publishing instead of Panini (historical publisher of sensei). They chose the English title The Devil's Lost Soul for the series. 2 volumes have already been published (Dec 13, 2012 but initially scheduled on November, and Jan 28) in 2 qualities: the regular one (without sleeve) at €4.40 and the deluxe one with sleeve, the colour pages, a better paper and not republished for €3.10 more.
Then in Germany: Carlsen Manga launched the series on Dec 4, 2012 under the title Devil from a Foreign Land at €6.95. The series counts 2 volumes, volume 3 will be released on May 29 and volume 4 on Sept 3rd.
In France: no fresh news from the publisher Pika however a blank page about Kaori Yuki exists on their site, see here.
